TMobile Dash won't read SIM card.

A SIM card that works on other phones won't show up on my Dash. When I turn it on, it isn't able to read SIM card. Is there any way to fix this? Thanks, please respond =/

the reader might be damaged. have you tried with other sim cards in it? try that and if it works then it might be the card reader. you can also try reformatting the sd card. Thats worked for me in the past. Like i said, try to use a diff. sd card in the dash and see if it works.

if problem persists take it to a corporate tmobile and have them look at it.

You started saying SD, I got confused.

I'll try to take it to T-Mobile then, I doubt they'll do much. Could I swap out SIM Readers?

when i say sd i mean memory card. and no you cant switch it lol.
